Which loaded on a rom? (XWJQ4???).
What is the exact problem?
GSM network = edge/2G
UMTS = 3G/Hspa
Settings/Wireless and network/Mobile networks/Network mode --> chose WCDMA only or GSM/WCDMA (auto).
The data may not be possible to go?
-To set correct APN settings!!

The exact problem is that my phone is gsm and when i inserts sim, it says "no sim inserted". But signals are shown there.
Its android 2.3.6(XXJPZ)
Netor Mode --> GPRS (yes its gprs and not wcdma/gsm)

3G Not working in Russia

sorry for my bad English, i use a translator
Bought yesterday on the phone and it worked 3g HSDPA, after flashed on Viper ROM only works in GSM!!! Help please ((crying:
Try changing the network mode to WCDMA only, Type *#*#4636#*#* in the dialer. Select phone information and scroll down to network type and then select WCDMA only.
You might also want to check your APN settings, If your network provider has different APNs for 2G and 3G, you will have to select the 3G one.

I have a sprint htc one m7
hboot 1.57 with S-On
FLashed to stock (Guru reset 3) and OTA updated to lollipop...
I am having the same problem, data network always stays on gsm .. tried everything from booting in safe mode to toggle airplane mode...
From dialing the code *#4636 blah blah and selecting the network mode...
Resetting APN settings for several times and several times of hard reset .. nothing solved the problem at all ..
Couldn't get anything to help me see H,H+ or 3G beside my network signal sign on my phone again ..... it always shows gsm and that's it...
It all happened after i flashed my phone to stock rom by using guru reset 3.x
I was using 3g successfully on bad boyz rom 5.x..
Now i even have got the OTA update for lollipop but my 3g doesn't seem to work at all .....
Please help !!!!
Couple of things:
1. The icons have probably changed. To get back the H and E symbols you'll have to edit the default.xml file. Navigate to system > customize > ACC > default.xml. I'd recommend downloading Root Browser to do this. Open the default.xml file using RB Note Editor and scroll all the way down. Around 20-25 lines from the bottom, you'll see the line
<Item type = "integer" name="sku_id">xx</item>
The xx will be a numeric value like 98 or something. Change this value to 42 if you're from Europe or 33 if you're from Asia. You can also change it to 0 which is the default HTC value. The line should now be:
<Item type = "integer" name="sku_id">42</item>
Make sure you save it before exiting. Reboot your phone and you should now see the E, 3G, and H symbols indicating your network connection.
2. Did you do a speedtest? What speeds are you getting?

Help Needed for Enabling LTE/4G on my HTC One

I own a HTC One M7_U and recently I've installed cynogenmod following the steps mentioned in one of the Thread of xdadevelopers.
After upgrading to Cynogenmod I am able to select the Preferred network to LTE (recommended) but not able to get 4G network on my phone. By searching few of the threads I found that using *#*#4636#*#* I can select the preferred network from there. But when I selected LTE only using this method, it automatically got changed to some other option (say WCDMA or LTE/WCDMA). I am only able to get 3G/H/H+ network.
Kindly tell me whether LTE/4G can be enable on my phone ? If yes, kindly tell me help me out with this problem.

The M7_U doesn't have an LTE radio, the faster you'll get is HSPA+
